摘要： Selected lengths of a first and second sheet material are advanced from their respective sources to a location and in such sequence where one of the materials is above a portion of the other. The upper material has an adhesive side opposed to the lower material. The selected lengths are severed simultaneously, which severing step also at least initially adheres the material together. Glue strips are placed on selected portions of the composite and registry is then made with a length of molded pipe insulation. The insulation is wrapped with the composite covering, the portion having the second strip being part of a flap for subsequent use in securing the insulation around the pipe.
